Eight different sets of simulated sequence data generated from model tree D with dmax = 1.0 and n = 600 were subjected to the bootstrap test. Original data sets a–d produced incorrect topologies, whereas data sets e–h generated the correct topologies. PB values before and after the / sign refer to those of the exhaustive search and the single-tree search bootstrap tests. The NJ tree was identical with the ME tree in all the eight cases.
